MELTDOWN! Please help: advise needed

[RallyGSX]

Help! My engine had a meltdown, and I want to be sure I don't repeat the problem... Anyway, I'm working on building a rally car one step at a time, Maybe I got the steps in the wrong order, or I have to do them all at once...
Mods so far:
Ported 16G Turbo, 2g Manifold, 2 1/2 " Turbo Back, Manual Boost controll set at 14 lbs., K+N and Hacked Aircan
JE 9:1 pistons, JUN flywheel w/out balance shafts
I have a 255 fuel pump and denso 660 injectors
The car was tuned w/ a logger and at the Dyno w/SAFC

I own, but have NOT installed: FMIC, -6 Fuel line and AFPR, Fuel Pump rewire hardware, 3" Turbo Back, Ported Evo Manifold and O2 Housing , Ported head w/ O/S SS Valves, HKS 264/272 Cams...etc.

The motor started having lots of crankcase blowby (filled oil catchcan very quickly), ran about 10-15 degrees too warm, some steam vapor came out of catchcan, then it started hesitating whenever I hit the gas and was retired. Upon inspection the cylinders were full of gas, #1 and 2 were at 90 lbs compression, others were at 145. After the head was removed it was discovered #1 and 2 pistons started to vaporize... #1 was worse than #2. The block and head were not damaged, it seems that the pistons started burning, alum. particles could not be found...
My first thought was fuel delivery problems, but it's not developing serious HP at this time, (and has a recent fuel filter change): 216 SAE HP, 235 lb-ft SAE Torque at the wheel...
Did I kill my car w/ fuel starvation?
Any Advise would be GREATLY APPRECIATED!!!

I will check w/JE tomorrow to clarify the correct clearance for their pistons. The instructions that come with the pistons stipulate a piston to cyl. wall clearance for "sport compacts" w/ 2.5 to 3.625" bore range as .0030 to .0036 as a minimum. The pistons are made of a non-silicon aluminum alloy, so they don't expand as much as a silicon containing piston. Also, JE says "clearances listed are minimum. Some applications such as supercharged, turbo, nitrous, and endurance applications may require additional clearance (.001 to .003"). So .0045 may not be too far off.
...
Any other Engine Building Procedures beneficial to a high performance turbo motor...

It's been a long time since I had JE custom make pistons for any of my or customer's cars. What I notice is .003"-.003.6" would be close if those were _per_ inch of bore and not the complete bore.

If those were his pistons that went through the melt down you should discuss this before ordering for he may have the exact specs on what you used even though they have distorted. This guy has been around the block like me more than once so he knows his business.

Do confirm if that's total bore or per inch spec. enquiring minds want to know.

Are you going to have him lighten them and or piston pins? Are you going to do any other lightning and polishing?
